[0002] The present invention relates to heat preservation technologies for textile fabrics, and in particular to a heat storage and preservation finishing liquor, and a preparation method therefor and use thereof.BACKGROUND
[0003] With the development of modern technology, a wide variety of technological products have emerged, and people are also increasingly pursuing garments incorporating advanced technological functions. Specifically, the heat preservation performance of down jackets is no longer limited to relying solely on down. Instead, more raw materials with functions such as far-infrared heating, light-absorbing and heat-generating properties are used to prepare fabrics with heat preservation capability, which are further combined with down filling to realize multiple heat preservation effects, thereby satisfying people's demands for warmth, lightness and fashion. At present, the heat-generating materials widely used in the industry mainly include graphene, nanoceramics, rare earth elements, and the like. Most of these materials act on fabrics in a single-component manner, resulting in limited heat retention and warming effects. Similarly, down jackets available on the market that utilize far-infrared heat preservation enable a temperature rise only by 1.5° C.-2.5° C., also providing a limited heat storage and preservation performance, which is far from sufficient to meet people's demands.SUMMARY
[0004] Objectives: the present invention aims to provide a heat storage and preservation finishing liquor, a preparation method for the finishing liquor and use of the finishing liquor in the preparation of a down jacket fabric, so as to improve the heat storage and preservation effects of down jackets.

Through the synergistic effects of solar energy absorption and reflection of thermal radiation, the fabric achieves heat storage, warming and heat preservation functions; and

[0017] The technical solutions of the present invention will be further described below.Example 1
[0018] A heat storage and preservation finishing liquor includes 13% of a silicon-boron polymer, 4% of a ceramic nanomaterial, 10% of an acidic hot lava material, 3% of a polysiloxane cross-linking agent, 8% of a dispersing agent, and 4% of an adhesive, with the balance being water; the silicon-boron polymer is a nanomaterial having a diameter of 200 nm-500 nm; the ceramic nanomaterial includes kaolin, calcium carbonate, calcium borate, aluminum oxide, iron oxide, and manganese oxide, with a ratio of 1:1:2:3:1:1; the acidic hot lava material includes aluminum silicate, with a content of 56%-65% and a density of 0.4 g / cm3-1.5 g / cm3; the dispersing agent includes fatty alcohol polyoxyethylene ether, fatty acid polyoxyethylene ester, naphthalene sulfonate, and polycarboxylic acid, with a ratio of 3:1:2:1; and the adhesive includes polyurethane, polyvinyl acetate, polyacrylate, and butadiene, with a ratio of 1:2:2:1.
[0019] A preparation method for the heat storage and preservation finishing liquor includes the following steps:
[0020] (a) mixing the above-mentioned raw materials according to the specified mass percentages, and stirring uniformly to obtain a mixed solution for later use;
[0021] (b) adding the mixed solution prepared in the step (a) to a vertical grinder, and adding zirconia beads for grinding, where the zirconia beads have a particle size of 1.2 mm-1.6 mm, and a mass of the zirconia beads is four times that of the mixed solution; and
[0022] (c) adding an appropriate amount of water during the grinding process until a particle size of the mixed solution becomes uniform, where a rotational speed of the grinding mill is 10,000 rpm-12,000 rpm, and grinding is performed for 45-90 minutes to prepare the heat storage and preservation finishing liquor.
[0023] The prepared heat storage and preservation finishing liquor maintains a particle size of 300 nm-500 nm, and the performance of the liquor is tested after being stored for a predetermined period of time. As shown in Table 1, after 12 months of storage, components of the finishing liquor remain stably mixed without settling, the viscosity is approximately 2.38 mPa·s, with a rate of change of the viscosity being 3.03%. Sufficient grinding ensures that the heat storage and preservation finishing liquor has a small particle size with good uniformity. In addition, under the action of the cross-linking agent, dispersing agent, and adhesive, the silicon-boron polymer, ceramic nanomaterial, and acidic hot lava material are uniformly dispersed in the solution, exhibiting good dispersibility and a low rate of change of the viscosity, thereby enabling the finishing liquor to maintain good stability.TABLE 1Stability test results of heat storageand preservation finishing liquorStorageState of finishingViscosity (mPa · s)Rate ofperiodliquor(Shear rate 200 s−1)change1monthNo settling2.310.00%4monthsNo settling2.351.73%8monthsNo settling2.414.33%12monthsNo settling2.383.03%
[0024] The prepared heat storage and preservation finishing liquor is applied to the preparation of down jacket fabrics. By applying to a treated common nylon fabric by means of rotary screen printing, a fabric having heat storage, warming and heat preservation functions is obtained. The silicon-boron polymer, ceramic nanomaterial, and acidic hot lava material interact with one another and exhibit complementary functions. Through the synergistic effects of solar energy absorption and reflection of thermal radiation, the fabric achieves heat storage, warming and heat preservation functions.TABLE 2Heat storage and warming performance test resultsof heat storage and preservation fabricHeat storage and warming20-minute temperatureRate ofperformancedifference / ° C.changeBefore washing20.80.00%After 5 washing cycles20.32.40%After 10 washing cycles19.84.81%TABLE 3Heat preservation performance test resultsof heat storage and preservation fabricHeat preservationFar infraredRate ofperformancereflectivitychangeBefore washing0.980.00%After 5 washing cycles0.980.00%After 10 washing cycles0.962.04%As shown in Table 2, the fabric achieves heat storage and a temperature rise by 20° C. or higher within 20 minutes; after the fabric is washed 10 times, the fabric still realizes heat storage and a temperature rise by 19.8° C. within 20 minutes, and the heat storage and warming performance is reduced by less than 5%, indicating that the fabric has excellent heat storage and warming performance. As shown in Table 3, a far-infrared thermal reflectivity of the fabric is more than 98%; after the fabric is washed 5 times, the reflectivity remains above 98%; and after the fabric is washed 10 times, the reflectivity is 96%, only decreasing by about 2%, indicating that the fabric maintains stable and efficient heat preservation effect.Example 2
[0026] A heat storage and preservation finishing liquor includes 10% of a silicon-boron polymer, 5% of a ceramic nanomaterial, 15% of an acidic hot lava material, 5% of a polysiloxane cross-linking agent, 10% of a dispersing agent, and 5% of an adhesive, with the balance being water; the silicon-boron polymer is a nanomaterial having a diameter of 200 nm-500 nm; the ceramic nanomaterial is kaolin; the acidic hot lava material is aluminum silicate, with a content of 56%-65% and a density of 0.4 g / cm3-1.5 g / cm3; the dispersing agent is fatty alcohol polyoxyethylene ether; and the adhesive is polyurethane, and polyvinyl acetate, with a ratio of 1:2.
[0027] A preparation method for the heat storage and preservation finishing liquor in this example is the same as that in Example 1, except that a mass of the zirconia beads is three times that of the mixed solution. The prepared heat storage and preservation finishing liquor maintains a particle size of 300 nm-500 nm. As shown in Table 4, after 8 months of storage, components of the finishing liquor remain stably mixed together without settling, and the viscosity is approximately 3.76 mPa·s, with a rate of change of the viscosity being 7.43%; and after 12 months of storage, the finishing liquor begins to settle, and the viscosity is approximately 3.82 mPa·s, with a rate of change of the viscosity being 9.14%. The heat storage and preservation finishing liquor prepared with this formulation exhibits a relatively high viscosity of 3.5 mPa·s-3.82 mPa·s and a large rate of change of the viscosity. Settling occurs after 12 months of storage, indicating poor stability.TABLE 4Stability test results of heat storageand preservation finishing liquorStorageState of finishingViscosity (mPa · s)Rate ofperiodliquor(Shear rate 200 s−1)change1monthNo settling3.500.00%4monthsNo settling3.602.86%8monthsNo settling3.767.43%12monthsSettling observed3.829.14%
[0028] The prepared heat storage and preservation finishing liquor is applied to the fabric preparation using the method as described in Example 1, thereby obtaining a fabric having both heat storage, warming and heat preservation functions. As shown in Table 5, the fabric achieves heat storage and a temperature rise by 16.8° C. within 20 minutes, indicating poor heat storage and preservation effects. After the fabric is washed 10 times, the heat storage and warming performance is reduced by 10.12%. As shown in Table 6, a far-infrared thermal reflectivity of the fabric is more than 92%; after the fabric is washed 5 times, the reflectivity remains above 92%; and after the fabric is washed 10 times, the reflectivity decreases by only about 2.17%. Therefore, the heat storage and preservation finishing liquor exhibits relatively poor heat storage and warming effects and stability, as well as a relatively low far infrared thermal reflectivity, but the reflectivity stability remains relatively high.TABLE 5Heat storage and warming performance test resultsof heat storage and preservation fabricHeat storage and warming20-minute temperatureRate ofperformancedifference / ° C.changeBefore washing16.80.00%After 5 washing cycles15.67.14%After 10 washing cycles15.110.12%TABLE 6Heat preservation performance test resultsof heat storage and preservation fabricHeat preservationFar infraredRate ofperformancereflectivitychangeBefore washing0.920.00%After 5 washing cycles0.920.00%After 10 washing cycles0.902.17%Example 3A heat storage and preservation finishing liquor includes 15% of a silicon-boron polymer, 3% of a ceramic nanomaterial, 6% of an acidic hot lava material, 1% of a polysiloxane cross-linking agent, 5% of a dispersing agent, and 3% of an adhesive, with the balance being water; the silicon-boron polymer is a nanomaterial having a diameter of 200 nm-500 nm; the ceramic nanomaterial is calcium carbonate and calcium borate, with a ratio of 1:2; the acidic hot lava material is aluminum silicate, having a content of 56%-65% and a density of 0.4 g / cm3-1.5 g / cm3; the dispersing agent is fatty alcohol polyoxyethylene ether and naphthalene sulfonate, with a ratio of 3:2; and the adhesive is polyacrylate and butadiene, with a ratio of 2:1.
[0030] A preparation method for the heat storage and preservation finishing liquor in this example is the same as that in Example 1, and the prepared heat storage and preservation finishing liquor maintains a particle size of 300 nm-500 nm. As shown in Table 7, after 4 months of storage, components of the finishing liquor remain stably mixed together without settling, and the viscosity is approximately 1.35 mPa·s, with a rate of change of the viscosity being 3.05%; after 8 months of storage, the finishing liquor begins to settle, and the viscosity increases more rapidly; and after 12 months of storage, the viscosity increases to about 1.45 mPa·s, with a rate of change of the viscosity up to 10.69%. The heat storage and preservation finishing liquor prepared with this formulation has a relatively low viscosity of 1.31 mPa·s-1.45 mPa·s and a large rate of change of the viscosity. Settling occurs after 8 months of storage, indicating poor stability.TABLE 7Stability test results of heat storageand preservation finishing liquorStorageState of finishingViscosity (mPa · s)Rate ofperiodliquor(Shear rate 200 s−1)change1monthNo settling1.310.00%4monthsNo settling1.353.05%8monthsSettling observed1.406.87%12monthsSettling observed1.4510.69%

After the fabric is washed 10 times, the heat storage and warming performance is reduced less than 2%, indicating good stability of the heat storage and warming effects. As shown in Table 9, a far-infrared thermal reflectivity of the fabric is more than 98%; after the fabric is washed 5 times, the reflectivity remains above 98%; and after the fabric is washed 10 times, the reflectivity decreases by only about 2.04%.

It is found that the finishing liquor prepared in Example 1 has moderate viscosity, low rate of change of the viscosity, and the best stability. The fabric prepared with this finishing liquor exhibits a change rate of heat storage and warming less than 5%, and the far infrared reflectivity decreases by approximately 2% after the fabric is washed 10 times. Main effective components of the finishing liquor are the silicon-boron polymer, ceramic nanomaterial, and acidic hot lava material, which have the heat storage and warming functions, and the ceramic nanomaterial also has the function of reflecting thermal radiation. The three components, in appropriate proportions, are grounded and mixed uniformly, and interact with each other to achieve the heat storage and warming functions of the fabric; and the nano-sized effective components are uniformly dispersed in the solution under the action of the cross-linking agent, dispersing agent, and adhesive, and the good dispersion performance ensures that the finishing liquor does not settle after prolonged storage, minimizes slight changes in viscosity, and maintains excellent stability.In Example 2, the content of the ceramic nanomaterial is high, with a small particle size and few surface defects, resulting in good adhesion to other components and high strength. In addition, the finishing liquor has a high content of the cross-linking agent and a high total solid content, resulting in an increase in viscosity. In Example 3, the content of the cross-linking agent is too low, resulting in weak interactions among the effective components, causing low viscosity and poor stability of the finishing liquor.
[0054] Analysis of the performance of the finishing liquors in Comparative Examples 1-3 shows that Comparative Example 1, which lacks silicon-boron polymer, exhibits the lower heat storage and warming performance and the worst stability, indicating that the silicon-boron polymer has the greatest impact on the heat storage and warming performance of the fabric. Comparative Example 2, which lacks ceramic nanomaterial, exhibits low far infrared reflectivity and poor heat preservation effects, indicating that the ceramic nanomaterial has the greatest effect on the far infrared reflectivity of the fabric. Comparative Example 3, which lacks acidic hot lava material, exhibits higher far infrared reflectivity and better heat preservation performance than Comparative Example 2; however, after the fabric is washed 10 times, the heat preservation effects decrease by 4.17%, indicating poor stability of heat preservation performance, this reveals that the acidic hot lava material has the greatest effect on the stability of the heat preservation of the fabric. Furthermore, components of the dispersing agent and adhesive in Comparative Examples 1 and 2 are relatively simple, resulting in uneven dispersion of the effective components and poor stability of the finishing liquor. Settling is significant after a prolonged period of storage, leading to a reduction in the content of effective components and an increase in rate of change of the viscosity, which in turn affect the content of effective components in the fabric and ultimately reducing the heat storage, warming and heat preservation performance of the fabric. The absence of any one of the three components adversely affects the dispersibility and stability of the finishing liquor, thus compromising the heat storage, warming and / or heat preservation performance of the fabric.TABLE 28Performance test results of fabrics prepared with heat storage and preservationfinishing liquor with different proportions of componentsPerformanceAfter 10 washing cyclesHeat storage andwarming performance(° C. / 20 Min)Heat preservationStabilityHeat storageperformanceSettlingViscosityRate ofand warmingRate ofRate ofS / Ntime(mPa · s)changeperformancechangeReflectivitychangeExample 1No2.31-2.383.03%19.84.81%0.962.04%settlingExample 2123.50-3.829.14%15.11.65%0.962.04%monthsExample 381.31-1.4510.69%17.91.65%0.962.04%monthsComparative82.25-2.5011.11%11.810.61%0.913.19%Example 1monthsComparative122.34-2.6011.11%12.64.55%0.863.37%Example 2monthsComparative122.37-2.609.70%11.87.81%0.924.17%Example 3monthsComparative42.55-2.9114.12%16.411.83%0.895.32%Example 4monthsComparative82.46-3.1026.2%17.96.28%0.907.29%Example 5monthsComparative42.39-2.9824.69%16.114.81%0.887.37%Example 6months
[0055] For Comparative Examples 4-6, the types and combinations of cross-linking agents, dispersing agents, and adhesives are changed. In Comparative Examples 4 and 6, only the type of dispersing agent is changed, while the amount of dispersing agent remains unchanged, and the cross-linking agent and adhesive also remain unchanged. The resulting finishing liquors begin to settle after 4 months of storage, indicating extremely poor stability of dispersion. Moreover, these finishing liquors exhibit poor heat storage and warming effects and low far infrared reflectivity, the fabrics prepared with these finishing liquors exhibit a decrease of 11.83-14.81% in the heat storage and warming performance and a decrease by 5.32-7.37% in the heat preservation after the fabrics are washed 10 times, indicating poor stability of the heat storage and warming effects and the reflectivity, and poor adhesion of the effective components to the fabric. In Comparative Example 5, the types of cross-linking agent, dispersing agent, and adhesive are changed, while the amount of these components remains unchanged, and the resulting finishing liquor suffers settling after 8 months of storage, indicating the poor stability of dispersion, great change in viscosity, poor heat storage and warming effects and low far infrared reflectivity. Furthermore, the fabric prepared with the finishing liquor exhibits a decrease by 6.28% in the heat storage and warming performance, and a decrease by 7.29% in the heat preservation effects after the fabric is washed 10 times.
[0056] These results demonstrate that different cross-linking agents, dispersing agents, and adhesives, as well as their combinations, when applied to the same proportion of heat storage, warming and heat preservation components, result in varying degrees of settling of the finishing liquor over time, and further causing significant changes in viscosity, dispersion, and dispersion stability of the finishing liquor. The dispersing agent ensures good dispersion of the finishing liquor and uniform distribution of effective components; the cross-linking agent and adhesive synergistically act on the effective components, maintaining stable dispersion and viscosity of the finishing liquor over a prolonged period of storage, and thereby locking the effective components in the finishing liquor. When applied to the fabric, more of these effective components are transferred to the fabric to achieve heat storage, warming and heat preservation effects. Furthermore, the synergistic effect of cross-linking agent, dispersing agent, and adhesive enhances adhesion of the effective components to the fabric surface, allowing the fabric to retain excellent heat storage, warming and heat preservation performance even after multiple washes.TABLE 29List of reagents used in the experimentsDescription of materialCAS No.ManufacturerSilicon-boron polymer12007-81-7Beijing Huawei Ruike ChemicalTechnology Co., LtdPolysiloxaneGX-Si-28Anhui Guibao Silicone Newcross-linking agentMaterials Co., Ltd.Fatty alcohol68131-39-5Aladdin Reagentspolyoxyethylene etherFatty acidA-110Jiangsu Hai'an Petrochemicalpolyoxyethylene esterPlantNaphthalene sulfonate1321-69-3Echemsrc.comPolycarboxylic acid24936-68-3Rhawn ReagentPolyurethane51852-81-4Guangzhou Difeng New MaterialsCo., Ltd.Polyvinyl acetate9003-20-7Wuhan Haorong BiotechnologyCo., Ltd.Polyacrylate9003-01-4Shanghai Yuanye Bio-technologyCo., Ltd.Butadiene106-99-0Hubei Chengfeng ChemicalCo., Ltd.6-hydroxydopamine28094-15-7Shanghai Yuanye Bio-technologyhydrochlorideCo., Ltd.Dibutyl phthalate84-74-2Zhejiang Bangfu BiotechnologyCo., Ltd.Trimethylolpropane33007-83-9Qingdao ZKHT Chemical Co.,triesterLtd.Polyvinylpyrrolidone9003-39-8Shanghai Chengyu BiotechnologyCo., Ltd.
